McIDAS images of 4-km resolution GOES-13 10.7 \u00c2\u00b5m IR channel data (above; click image to play animation)<\/em><\/strong> showed Category 1 Hurricane Ernesto<\/a><\/strong> as it approached the far southeast coast of Mexico during the late afternoon and eary evening hours on 07 August 2012<\/strong>. The GOES-13 satellite had been placed into Rapid Scan Operations mode, providing images as frequently as every 5-10 minutes (vs the standard 15-minute image interval). Cloud top IR brightness temperatures of -80\u00c2\u00ba C and colder were highlighted by the violet color enhancement.<\/p>\n

AWIPS images of the 1-km resolution POES AVHRR Cloud Top Temperature (CTT) product indicated that CTT values were as cold as -87\u00c2\u00ba C at 02:12 UTC and -86\u00c2\u00ba C at 03:27 UTC (below)<\/em><\/strong>.<\/p>\n

The 1-km resolution POES AVHRR Cloud Top Height (CTH) product showed that the highest cloud tops were around 16 km (below)<\/em><\/strong>.<\/p>\n

According to the 00:00 UTC \/ 08 August rawinsonde data from Belize City (below),<\/em><\/strong> the height of the tropopause was 15.8 km, with the air temperature at and just above the tropopause around -82\u00c2\u00ba C. Note the nearly saturated profile of the tropical air mass, with a total precipitable water value of 2.58 inches.<\/p>\n

Since the Moon was in the Waning Gibbous phase (61% of full),<\/em> there was enough reflected moonlight to allow a Suomi NPP VIIRS Day\/Night Band image (below)<\/strong><\/em> to reveal the well-defined circulation of Ernesto as it was moving inland across the Yucatan Peninsula of Mexico at 06:54 UTC (1:54 am local time)<\/em>. Note the bright areas of city lights along the coastal areas (most notably Campeche, Merida, and Cancun)<\/em> that could be seen through the relatively thin edges of the cirrus canopy.<\/p>\n
